Germany just made open file formats the mandatory standard for digital sovereignty.
If you want to know who really controls your data, look at your file formats.
Germany just made a massive move that proves they are finally taking back control: as part of the "Deutschland-Stack," they are making the Open Document Format (ODF) a mandatory, binding standard for public authorities. Proprietary alternatives will no longer be treated as equal options.
For a long time, we've talked about "digital sovereignty" as an abstract goal. But this move tackles the reality: establishing an open format is the absolute foundation of it all.
Here is why this matters:
When you rely on proprietary formats, you aren't just buying software; you are locking yourself into a vendor's ecosystem. You can't simply swap out a provider when you want to, because your entire archive of documents relies on their specific code to open properly. It promotes a silent, expensive vendor lock-in.
Open formats completely flip the script.
They guarantee that the documents a government creates today can still be read, edited, and processed decades from now, regardless of which software suite is being used. It allows organizations to replace vendors easily, creating actual competition and leveling the playing field for Open Source solutions.
And Germany isn't just making recommendations, they are changing the rules of the game. Just days ago, the government overhauled its IT procurement standards, legally declaring Open Source as the new default for public software projects. They are actively dismantling the bureaucratic barriers that kept proprietary vendors in power.
The Digital Sovereignty and Open Source movements are gaining serious institutional momentum. There will be hurdles, like retraining staff and dealing with legacy systems, but drawing a hard line on file formats is the only way to break the status quo.
But here is what I find fascinating: historically, this momentum has been driven almost entirely by the public sector. We are seeing it in places like Denmark, the federal state of Schleswig-Holstein, and even Trinidad and Tobago.
The private sector has lagged far behind, until right now.
We are finally seeing the corporate world wake up as the financial pain of lock-in becomes too great. Governments are making the switch for digital sovereignty; private companies are finally doing it to survive the squeeze of proprietary licensing.
